| description | The utility model relates to a S type directional well drilling tool technical field is a S type directional well drag reduction drilling tool. Including drilling rod, drill collar, screw rod and thedrill bit that is the S form, the drilling rod, drill collar, screw rod and the drill bit top -down that are S form be in the same place according to preface fixed mounting, and the drilling rod thatis the S form includes flex point section and flex point section down, the outside of last flex point section flex point section under and respectively fixed mounting have the gyro wheel stabilizer. The utility model has the advantages of reasonable and compact structure, convenient to use, through the roll of gyro wheel on the gyro wheel stabilizer, the drilling rod that will be S form and the sliding friction of the wall of a well change the rolling friction of gyro wheel and the wall of a well into to reduce the frictional resistance of drilling tool.
